DETAILED DESCRIPTION

The present invention pertains to substituted phenyl-quanidines, to methods for their preparation and use as anthelmintics, and to compositions thereof useful in such use.

Various N-formyl- and N-alkanamido-N',N"-bis(carbalkoxy)quanidines are described in German Offenlegungschrift No. 2,117,293 as having anthelmintic properties. The effect of these properties however is relatively weak.

The present invention pertains to anthelmintic phenyl-guanidines of the formula: ##STR1## wherein X is oxygen, sulfur, sulfinyl or sulfonyl;

One of R and R¹ is --COR⁴ and the other is ##STR2## in which R⁴ is hydrogen or an unsubstituted or substituted alkyl, cycloalkyl, alkoxy, aryl or amino group;

R⁵ is an unsubstituted or substituted alkyl, alkenyl or alkynyl group; and

R⁶ is hydrogen or an unsubstituted or substituted alkyl, cycloalkyl, alkenyl, alkynyl, aryl, alkoxy, alkenyloxy or alkynyloxy group; and

Each of R² and R³ independent of the other is hydrogen, halogeno, cyano, or an unsubstituted or substituted alkyl, alkoxy, alkylthio, halogenoalkyl, amino or carbalkoxy group.

The foregoing guanidines can be depicted in several tautomeric forms, as shown below for the guanidine moiety only: ##STR3##

While for consistency and conciseness the structural formulas have been shown in only one of the foregoing ways, it will be appreciated that the actual compounds are inclusive of all tautomeric forms.

In the present context, the optionally-substituted alkyl groups embraced by R², R³, R⁴, R⁵ and R⁶ are straight- or branched hydrocarbon chains containing from 1 to 6, especially from 1 to 4, carbon atoms, as for example methyl, ethyl, n- and i-propyl, and n-, i- and t-butyl groups.

The compounds are prepared by a process which comprises (a.) reacting a compound of the formula: ##STR4## wherein R², R³ and R⁴ are as defined above, with an isothiourea-S-alkyl ether of the formula: ##STR5## in the presence of an acid and in an inert organic solvent, or (b.) treating a compound of the formula: ##STR6## wherein R, R¹, R² and R³ are as defined above and X is sulfur with an oxidizing agent to yield the corresponding compound wherein X is sulfinyl or sulfonyl.

The first of the foregoing two reactions is generally conducted in an inert organic solvent, generally a polar solvent such as an alcohol, as for example methanol, ethanol or isopropanol, a ketone such as acetone or methylethyl ketone, an alkanoic acid such as acetic acid, an ether such as ethyl ether and tetrahydrofuran. The medium may be aqueous, utilizing one of the foregoing water-miscible solvents in combination with water. The reaction is carried out at a temperature of from 0° to 120° C, preferably from 30° to 100° C, preferably at the boiling point of the solvent, in the presence of an organic or inorganic acid such as hydrochloric acid, sulfuric acid, nitric acid, formic acid, acetic acid, p-toluenesulfonic acid, and the like. Equimolar amounts of reactants are generally employed although this can vary by about ± 20% without significant effect on the yield. An alkylmercaptan is formed as a by-product and the desired product is obtained by cooling the reaction mixture and collecting the solid which can be purified if desired by conventional techniques such as recrystallization.

In the foregoing second reaction, a compound of the present invention wherein X is sulfur is treated with one molar equivalent of an oxidizing agent to yield the corresponding compound where X is sulfinyl or with two moles to yield the corresponding compound where X is sulfonyl. The oxidizing agents include organic peroxoacids, such as peracetic acid, performic acid, perbenzoic acid, m-chlorobenzoic acid, monoperphthalic acid and the like; inorganic peroxides, such as hydrogen perioxide; organic acids dissolved in water or otherwise diluted; inorganic oxidation agents such as chromic acid, nitric acid, potassium permanganate, chlorine or bromine; halo oxy acids such as hypochlorous acid, chlorous acid, chloric acid, perchloric acid, tert.-butyl hypochlorite, methyl hypochlorite, tert.-butylchromate and the like; or N-haloimides such as N-chloro-succinimide and N-bromo-succinimide, N-halo sulphonic acid amides or N-halo carboxylic acid amides.

Reaction conditions are selected, in a manner known to the art, so that oxidation potential is adjusted for the production of either sulfoxides or sulfones.

Many of the thioureas used as starting materials in the first reaction are known (see Olin and Dains, J. Amer. Chem. Soc. 52, 3326 (1930) and U.S. Pat. No. 2,993,502) while others can easily be obtained by known processes. The thioureas are generally prepared from known N-acylthioureas [see, e.g. "Berichte der deutschen Chemischen Gesellschaft", 6, 755 (1873); Ann, Chim. (5) 11, 313 (1877); J. Amer. Chem. Soc. 62, 3274 (1940)], which are reacted with alkylating agents such as alkyl halides, alkyl sulphates or alkyl sulphonates to give the corresponding S-alkyl-N-acyl-isothioureas [see, e.g. J. Org. Chem. 30, 560, (1965); Chem. Pharm. Bull. (Tokyo), 9, 245, (1961)]. These S-alkyl-N-acyl-isothioureas are then reacted with halogenoformic acid esters or with pyrocarbonic acid dialkyl esters [see, e.g. Ber. dtsch, chem. Ges. 71, 1797 (1938)] to give the S-alkyl-N-acyl-N'-alkoxycarbonyl-isothioureas, which corresponds to the known substitution of S-alkyl-isothioureas with chloroformic acid alkyl esters [see, e.g. J. Amer. Chem. Soc. 52, 3326 (1930 )].

The following are typical isothioureas which can be employed in accordance with the process of this invention: N,N'-bis-methoxycarbonyl-S-methyl-isothiourea (melting point 99°-100° C), N,N'-bis-ethoxycarbonyl-S-methyl-isothiourea (melting point 50°-51° C), N-ethoxycarbonyl-N'-propionyl-S-methyl-isothiourea (melting point 92°-94° C), N-methoxy-carbonyl-N'-propionyl-S-methyl-isothiourea (melting point 97°-99° C), N-methoxycarbonyl-N'-ethoxyacetyl-S-methyl-isothiourea (melting point 69°-70° C), N-methoxycarbonyl-N'-cyclohexylcarbonyl-S-methyl-isothiourea (m.p. 67°-68° C), N-methoxycarbonyl-N'-phenylacetyl-S-methyl-isothiourea (m.p. 55°-56° C), N-ethoxycarbonyl-N'-benzoyl-S-methyl-isothiourea (m.p. 79°-80° C), N-ethoxycarbonyl-N'-methoxycarbonyl-S-methyl-isothiourea (m.p. 69° C), N-allyloxycarbonyl-N'-methoxycarbonyl-S-methyl-isothiourea, N-propinyloxycarbonyl-N'-methoxycarbonyl-S-methyl-isothiourea, N,N'-bis-allyloxycarbonyl-S-methyl-isothiourea and N,N'-bis-propinyloxcarbonyl-S-methyl-isothiourea.

Most of the 2-aminoanilide starting materials are known. Those that are not previously known can be readily prepared by methods analogous to those disclosed in the literature. For example, a 2-nitroaniline having the appropriate substituent in the 4- or 5-position, e.g., phenoxy, phenylthio, phenyl-sulfinyl or phenylsulfonyl, can be N-acylated with an acid chloride of the formula R⁴ COCL to yield the corresponding 2-nitro-4- or 5-substituted anilide which is hydrogenated as with Raney nickel to yield the 2-amino-4- or 5-substituted anilide. The 2-nitroanilines having a phenylsulfinyl or phenylsulfonyl group in the 4- or 5-positions can also be obtained from the corresponding phenylthio compounds through controlled oxidation analogous to that described above, e.g. using hydrogen peroxide in acetic anhydride or perbenzoic acid in dioxane or chloroform, to yield the sulfinyl compound, or hydrogen peroxide in glacial acetic acid to yield the sulfone. The 4- and 5-phenylsulfonyl-2-nitroanilines can also be obtained by the reaction of a sodiumbenzenesulfinate with a 4- or 5-chloro-2-nitroaniline as for example dimethylformamide at about 140° C.

The compounds prepared in accordance with the invention show a surprisingly improved action against one or more of the following nematodes and cestodes:

1. Hookworms (for example Uncinaria stenocephala, Ancylostoma caninum and Bunostomum trigonocephalum).

2. Trichostrongylidae (for example Nippostrongylus muris, Haemonchus contortus, Trichostrongylus colubriformis and Ostertagia circumcincta).

3. Strongylidae (for example Oesophagostomum columbianum).

4. Rhabditidae (for example Strongyloides ratti).

5. Ascaridae (for example Ascaris suum, Toxocara canis and Toxascaris leonina).

6. Threadworms (for example Aspiculuris tetraptera).

7. Heterakidae (for example Heterakis spumosa).

8. Whipworms (for example Trichuris muris).

9. Filariae (for example Litomosoides carinii and Dipetalonema witei).

10. Cestodes (for example Hymenolepis nana, Taenia pisiformis and Echinococcus multilocularis).

The action of the compounds of the invention can be conveniently observed in vivo by oral and patenteral administration to test animals heavily infested with parasites.

Hookworm test / sheep and dogs

Sheep experimentally infected with Bunostomum trigonocephalum were treated after the end of the prepatency period of the parasites. The amount of active compound was administered orally as pure active compound in gelatin capsules.

Dogs experimentally infected with Uncinaria stenocephala or Ancylostoma canium were treated after the end of the pre-patency period of the parasites. The amount of active compound was administered orally as pure active compound in gelatin capsules.

The effectiveness is determined by counting the worms expelled after the treatment and, after dissection, the worms surviving in the test animals, and calculating the percentage of worms expelled.

The active compounds tested, the dosages used and the action can be seen from the table which follows, which lists the active compounds and the minimum dosage, in mg of active compound per kg of body weight of the test animal, which reduces the worm infection of the test animal by more than 90%.

Nippostrongylus muris-rats

Rats experimentally infected with Nippostrongylus muris were treated after the end of the pre-patency period of the parasites. The amount of active compound was administered orally as an aqueous suspension.

The effectiveness of the preparation is determined by counting, after dissection, the worms which have remained in the test animal, in comparison to untreated control animals, and calculating the percentage action therefrom.

Table 2 lists the active compounds and the minimum dosage which reduces the worm infection of the test animals by more than 90%, in comparison to related preparations.

Stomach and intestine worm test/sheep

Sheep experimentally infected with Haemonchus contortus or Trichostrongylus colubriformis were treated after the end of the pre-patency period of the parasites. The amount of active compound was administered orally as pure active compound in gelatine capsules.

The effectiveness is determined by quantitatively counting the worm eggs, excreted with the faeces, before and after the treatment.

Complete cessation of the excretion of eggs after the treatment denotes that the worms have been expelled or have been so damaged that they can no longer produce any eggs (effective dose).

The active compounds tested and the effective dosages (minimum effective dose) can be seen from Table 3.

Ascarid test/dogs and rats

Dogs naturally or experimentally infected with Toxascaris leonina were given the amount of active compound administered orally as pure active compound in gelatine capsules.

The effectiveness is determined by counting the worms expelled after the treatment and, after dissection, the worms surviving in the animals, are calculated in percentage of worms expelled.

Rats experimentally infected with Ascaris suum were treated 2 to 4 days after infection. The amount of active compound was administered orally as an aqueous suspension.

Hymenolepis nana/mice

Test animals experimentally infected with H.nana are treated after the end of the pre-patency of the parasites. The amount of active compound is administered orally as an aqueous suspension.

The effectiveness of the preparation is determined by counting, after dissection, the worms which have remained in the test animal in comparison to untreated control animals and calculating the percentage action therefrom. The results are shown in Table 6.

                                      Table 6                                      __________________________________________________________________________                               Minimum effective dose                               Compound                  (Red. >90%) in mg/kg                                 __________________________________________________________________________     F1                                                                                 ##STR68##             500                                                  F2                                                                                 ##STR69##             500                                                  The compounds of the invention are employed to combat helmintic                infestations, both prophylactically and therapeutically, in humans and         other animals through administration thereto of an anthelmintically            effective amount of one or more compounds. Generally such an amount will       range from about 0.1 mg/kg to about 50 mg/kg of body weight, depending         upon the stage and severity of the infestation. This range is of course        merely a guideline and the actual dose should be titrated to the               recipient keeping in mind his age, general health and body weight, the         response to treatment and the type of formulation. At times less than 0.1      g/kg will suffice while at others more than 50 mg/kg can be indicated.         The total daily dose thus will generally be from about 5 mg to about 5 g, 

The compounds of the present invention are administered parenterally or orally in any of the usual pharmaceutical forms. These include solid and liquid oral unit dosage forms such as tablets, capsules, powders, suspensions, solutions, syrups and the like, including sustained release preparations, and fluid injectable forms such as sterile solutions and suspensions. The term unit dosage form as used in this specification and the claims refer to physically discrete units to be administered in single or multiple dosage to animals, each unit containing a predetermined quantity of active material in association with the required diluent, carrier or vehicle. The quantity of active material is that calculated to produce the desired therapeutic effect upon administration of one or more of such units.

Powders are prepared by comminuting the compound to a suiable fine size and mixing with a similarly comminuted diluent pharmaceutical carrier such as an edible carbohydrate material as for example, starch. Sweetening, flavoring, preservative, dispersing and coloring agents can also be present.

Capsules are made by preparing a powder mixture as described above and filling formed gelatin sheaths. A lubricant such as talc, magnesium stearate and calcium stearate can be added to the powder mixture as an adjuvant before the filling operation; a glidant such as colloidal silica may be added to improve flow properties; a disintegrating or solubilizing agent may be added to improve the availability of the medicament when the capsule is ingested.

Tablets are made by preparing a powder mixture, granulating or slugging, adding a lubricant and disintegrant and pressing into tablets. A powder mixture is prepared by mixing the compound, suitably comminuted, with a diluent or base such as starch, sucrose, kaoline, dicalcium phosphate and the like. The powder mixture can be granulated by wetting with a binder as syrup, starch paste, acacia mucilage or solutions of cellulosic or polymeric materials and forcing through a screen. As an alternative to granulating, the powder mixture can be run through the tablet machine and the resulting imperfectly formed slubs broken into granules. The granules can be lubricated to prevent sticking to the tablet forming dies by means of the addition of stearic acid, a stearate salt, talc or mineral oil. The lubricated mixture is then compressed into tablets. The medicaments can also be combined with free flowing inert carriers and compressed into tablets directly without going through the granulating or slugging steps. A protective coating consisting of a sealing coat of shellac, a coating of sugar or polymeric material and a polish coating of wax can be provided. Dyestuffs can be added to these coatings to distinguish different unit dosages.

Oral fluids such as syrups and elixirs can be prepared in unit dosage form so that a given quantity, e.g., a teaspoonful, contains a predetermined amount of the compound. Syrups can be prepared by dissolving the compound in a suitably flavored aqueous sucrose solution while elixirs are prepared through the use of a non-toxic alcoholic vehicle. Suspensions can be formulated by dispersing the compound in a non-toxic vehicle in which it is insoluble.

Fluid unit dosage forms for parenteral administration can be prepared by suspending or dissolving a measured amount of the compound in a non-toxic liquid vehicle suitable for injection such an aqueous or oleaginous medium and sterilizing the suspension or solution. Alternatively a measured amount of the compound is placed in a vial and the vial and its contents are sterilized and sealed. An accompanying vial or vehicle can be provided for mixing prior to administration.

The following examples will serve to further illustrate the compound of the invention and the methods of preparation without being a limitation on the scope thereof, the scope being defined solely by the appended claims.

EXAMPLE 15 ##STR91##

Using the method described in Example 3, 14.4 g (0.05 mol) of 2-amino-5-phenylsulphonyl-propionanilide of melting point 137° C and 10.3 g (0.05mol) of N,N'-bis-methoxycarbonyl-isothiourea-S-methyl -ether give 12.7 g of N-(2-propionamido-4-phenylsulphonyl)-N',N"-bis-methoxycarbonyl-guanidine of melting point 197° C.

Substituting 2-amino-5-phenylsulphonylbutyranilide and 2-amino-5-phenylsulphonylmethoxyacetanilide, there are obtained N-(2-butyrylamido-4-phenylsulphonyl-phenyl)-N',N"-bis-methoxycarbonyl-guanidine, m.p. 180° C, and N-(2-methoxyacetamido-4-phenylsulphonylphenyl)-N',N"-bis-methoxycarbonyl-guanidine, m.p. 180° C, and N-(2-methoxyacetamido-4-phenylsulphonylphenyl)-N',N"-bis-methoxycarbonyl-guanidine, m.p. 142°C.

EXAMPLE 16

In a fashion analogous to Example 15 the corresponding N,N'-disubstituted isothiourea-S-methyl-ethers and 2-amino-5-phenylsulphonylanilides are reacted to yield the following compounds:

EXAMPLE 17 ##STR95##

14.4g (0.05mol) of 2-amino-4-phenylsulphonyl-butyranilide (melting point 143°-145°) in 100 ml of methanol are heated with 10.3 g (0.05mol) of N,N'-bis-methoxycarbonyl-isothiourea-S-methyl-ether, with addition of 1 g of p-toluene-sulphonic acid, for 3hours. After working up analogously to Example 3, 15.8 g of N-(2-butyramido-5-phenylsulphonyl-phenyl)-N',N"-bis-methoxycarbonyl-guanidine of melting point 173° C are obtained.

EXAMPLE 18

In a fashion analogous to Example 17, the corresponding N,N'-disubstituted isothiourea-S-methyl-ethers and 2-amino-5-phenylsulphonylanilides are reacted to yield the following compounds:
